Answer:
the level of water will rise
Explanation:
The density of stones is more than the density of water. So, when the stones are dropped into the water, the stone replaces the volume of water equal to the volume of stones.
Answer:
Spills out 10cm³ of wather.
Explanation:
The ball being submerged halfway in the full glass of water will spill a volume of water equal to the volume of the ball that is being submerged, because the entire volume of the submerged ball was previously occupied by water and is not compressed should move out of the glass.This volume will be 10cm³ since the total of the ball is 20cm³ and it is submerged halfway.
Terminal velocity is when something stops accelerating and just goes at one constant speed so if you put it into a sentence it would be like the rock falling off of the cliff did not accelerate instead it stayed at a terminal velocity
It relates because<span> the </span>energy<span> of an object to its </span>mass and since fission requires energy to do so, e=mc^2 relates to it.
